Abstract
A solar energy collector is made up of a plurality of flexible sheets separated by a plurality of extruded flexible spacer members adhered to the sheets in parallel spaced relationship forming channels between the spacer members. The bottom sheet or middle sheet is light absorbing while the top sheet or sheets are light transmitting and all of the sheets and spacer members are desirably formed of silicone rubber or resin, the sheets being reinforced with glass fiber mesh if desired.
Claims4
A solar energy collector comprising a first sheet of flexible material,
- a plurality of extruded flexible spacer members adhered to the bottom of said first sheet in substantially parallel spaced relationship, and
- a second sheet of flexible material adhered to the bottoms of said spacer members,
- whereby said spacer members and said sheets define a plurality of parallel fluid paths for passage of heat absorbing fluid therethrough to transmit heat from said collector;
- and further comprising a second plurality of extruded flexible spacer members adhered to the top of said first sheet in substantially parallel spaced relationship, and
- a third sheet of solar energy transmitting material adhered to the tops of said second plurality of spacer members.
